Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Jiangsu, contains 138 records (15.5% of this 891-record cohort). The remaining cohort contains 753 records. The comparison concerns archive composition.

The recorded industry label Next-generation information technology accounts for 95.7% here (853/891), compared with 27.1% in the parent set (5,226/19,297), an absolute gap of 68.7 percentage points.

300/891 companies link to pages with existing source-supported excerpts (33.7% of the cohort). The other 591 records remain usable for archive composition, but do not support new operating case studies.

17 keyword candidates match only a company name, with no matching term in recorded products or sub-industry fields. Product evidence is needed before treating these as operating businesses in this segment.

Ratio of label participation, not market share; multi-label counts overlap.

Excluding this cohort, the recorded industry label Next-generation information technology covers 4,373/18,406 remaining records (23.8%), an absolute gap of 72.0 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 34 labels; the top 3 contain 359/891 records (40.3%).Other known labels contain 532 records.

For 891 records with known labels, the effective category count is 11.4, versus 34 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 24 others are included in the calculations above.

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.

An ID may match several fields, so counts may exceed the cohort total. Matches establish search relevance only.

Among the translated non-broad query terms, “communication equipment” has the most matches: 841/891. Name, product and sub-industry fields match 10, 774 and 68 records respectively; the largest field is product field. Fields can overlap, and a term remains a search link rather than verified business activity.

Selected query termCandidates/shareName matchesProduct fieldSub-industry
communication equipment841 · 94.4%1077468
satellite communications27 · 3.0%1270

Selected broad terms and specific segment terms, not the full query. Terms and fields can overlap and must not be summed. Counts show lexical sensitivity; no records are removed without primary evidence.

17 candidates match only a name, or lose all product-field matches after the full company name is removed while sub-industry also has no hit. This transparent string test locates copied company descriptions; it does not establish that a company does not operate the business.

Intersection with 2026 local lists

180 of this cohort’s 891 records link through existing company-ID mappings to 2026 lists from all jurisdictions (20.2%). This intersection measures list linkage, not successful recognition or company growth.

Recorded roles and delivery checks

Check terminal direction separately from system delivery

The Communication equipment and networks label covers 64 records (7.2% of this cohort). This archive clue raises a verification question about Complete systems with use-specific delivery documentation; it does not establish that these companies already deliver it.
